Notes:
*Standard boundary conditions that apply to all system KPIs: input of AC power and tap water; output of hydrogen meeting ISO 14687-2 at atmospheric pressure. Correction factors may be applied if actual boundary conditions are different.
From 3 and 4 please refer to table 2.1 ( similar conditions as for alkaline technology)
5. Reversible efficiency is defined as the electricity generated in reversible mode of the electrolyser, divided by the lower heating value of hydrogen consumed.
6. Reversible capacity is defined as a percentage of the electric capacity in fuel cell mode in relation to the electrolyser mode
7. Degradation at thermo-neutral conditions in percent loss of production-rate (hydrogen power output) at constant efficiency. Note this is a different definition as for low temperature electrolysis, reflecting the difference in technology.
